*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). 
 CI: Confidence interval;
GRADE Working Group grades of evidence 
 High quality: Further research is very unlikely to change our confidence in the estimate of effect. 
 Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. 
 Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. 
 Very low quality: We are very uncertain about the estimate.

1 No adequate explanation of randomisation and allocation concealment 
 2 CI crossed line of no effect and substantive harm and benefit.
